Some of us have an annual budget of less than $2000 - for the entire program, including all supplies, reeds, oils, and the like. If you have percussionists all needing their own set of snare sticks, mallets, and timpani mallets due to "no sharing" mandates from a district that also provides all equipment, you're not talking $10 a pair - you're talking $50+ per kid in the program. Multiply by 40 percussionists, which isn't out of the realm of possibilities for a middle school band, and there's the entire annual budget on just separate sets of sticks.
The suggestion wasn't "how do I spend a ton more money" it was "how do I sanitize drumsticks." Not everyone has the means to just "get each kid their own pair."
To Art: There are several ways to sanitize. You can use an alcohol or Lysol solution which kills germs, but can denature and/or degrade your sticks. You could use antibacterial (chlorine or alcohol-based) wipes on them regularly, which gets expensive - wipes aren't cheap in bulk.
Or you could use light and/or heat. Get a hand-held powered UV sterilizing light (admittedly, about $100 on Amazon) and run it over your sticks appropriately after every rehearsal/class. UV light and heat kill viruses quite effectively.
